[Ougon Musou Kyoku Cross] J's combo video #1

If you look at the last combo, you'll understand why the game doesn't let you choose Black Battler in online match.

In the video description, J also mentioned that
- There're many combos that only work on certain characters in Cross.
- He did beat CPU Black Battler. (Hard mode, I assume.) He saw some patterns. He'll upload it later because the game was just released. It's too soon. He doesn't want to spoil the fun.
